Solving bi-directional soliton equations in the KP hierarchy by gauge transformation
Jingsong He, Yi Cheng, Rudolf A. Roemer
We present a systematic way to construct solutions of the (n=5)-reduction of the BKP and CKP hierarchies from the general tau function of the KP hierarchy. We obtain the one-solito…
Weak disorder expansion for localization lengths of quasi-1D systems
Rudolf A. Roemer, Hermann Schulz-Baldes
A perturbative formula for the lowest Lyapunov exponent of an Anderson model on a strip is presented. It is expressed in terms of an energy dependent doubly stochastic matrix, the…
Effects of Scale-Free Disorder on the Anderson Metal-Insulator Transition
Macleans L. Ndawana, Rudolf A. Roemer, Michael Schreiber
We investigate the three-dimensional Anderson model of localization via a modified transfer-matrix method in the presence of scale-free diagonal disorder characterized by a disorde…
Anisotropic Quantum Hall Matrix Model
Ahmed Jellal, Rudolf A. Roemer, Michael Schreiber
We consider the anisotropic effect in the quantum Hall systems by applying a confining potential that is not of parabolic type. This can be done by extending Susskind--Polychronako…
Fluctuating Hall resistance defeats the quantized Hall insulator
Philipp Cain, Rudolf A. Roemer
Using the Chalker-Coddington network model as a drastically simplified, but universal model of integer quantum Hall physics, we investigate the plateau-to-insulator transition at s…
Thermoelectric Properties of Disordered Systems
R. A. Roemer, A. MacKinnon, C. Villagonzalo
The electronic properties of disordered systems have been the subject of intense study for several decades. Thermoelectric properties, such as thermopower and thermal conductivity,…
